5.16.4.8 Interrupt Sources
5.16.4.9 Peripheral DMA Request
There are three interrupt sources of ADC interrupt. When an ADC operation mode finishes its
conversion, the A/D conversion end flag, ADF, will be set to 1. The CMPF0 and CMPF1 are the
compare flags of compare function. When the conversion result meets the settings of
ADCMPR0/1, the corresponding flag will be set to 1. When one of the flags, ADF, CMPF0 and
CMPF1, is set to 1 and the corresponding interrupt enable bit, ADIE of ADCR and CMPIE of
ADCMPR0/1, is set to 1, the ADC interrupt will be asserted. Software can clear the flag to revoke
the interrupt request.
When A/D conversion is finished, the conversion result will be loaded into ADDR register and
VALID bit will be set to 1. If the PTEN bit of ADCR is set, ADC controller will generate a request to
PDMA. User can use PDMA to transfer the conversion results to a user-specified memory space
without CPU's intervention. The source address of PDMA operation is fixed at ADPDMA, no
matter what channels was selected. When PDMA is transferring the conversion result, ADC will
continue converting the next selected channel if the operation mode of ADC is single scan mode
or continuous scan mode. User can monitor current PDMA transfer data through reading
ADPDMA register. If ADC completes the conversion of a selected channel and the last conversion
result of the same channel has not been transferred by PDMA, OVERUN bit of the corresponding
channel will be set and the last ADC conversion result will be overwrite by the new ADC
conversion result. PDMA will transfer the latest data of selected channels to the user-specified
destination address.
